The U.K.-based model, 24, has recently uploaded "real-life" images on Instagram showing double chins, chipped nail polish and facial hair removal. The experiment was inspired by Australian teen Essena O'Neill, who decided to abandon Instagram due to the images' disconnect from actual life.

For Sanders, the project has sparked a dialogue about the way people present themselves on social media.

"I wanted to see what would actually happen if I stopped posting glamorous photos, and shared stuff that you wouldn't normally even share with your friends, stuff that is taboo, stuff that was quite crude, all that kind of stuff," Sanders told People. "Personally I think Instagram is so fake - the amount of filters, the airbrushing - so I thought it would be interesting."
